In my work as a home inspector I see a great deal of deck damage from barbecues. IOt is quite common to see deck surfaces and adjacent walls with scorch marks and melted vinyl siding. Luckily most of these cases don't end up in fires, but they do cause some expensive damage. For example, when waterproof deck surfaces are damaged in one area it may be necessary to replace at least some of the special plywood underlayment and re-surface the entire deck. And when vinyl siding is damaged in one area finding some matching replacement material can be very difficult.
Another type of damage from BBQs comes from grease and other spills around the BBQ area. Soft woods like western red cedar and redwood can absorb such liquids and the resulting stains are difficult to remove.
So here are some tips that should help in avoiding such problems:
Have a great BBQ!
